What is a Fen?

Fens are an important wetland type in the mountains of California. Fens are permanently saturated wetlands, receiving significant water and nutrients from a ground source of water. Ground water fed fens are widespread in the California mountains of the Sierra Nevada, coast range, and southern Cascades.
